LUBRICATOR.

Specification of Letters Patent. Patented Sept; 1911.

Application filed December 24. 1910. Serial No. 599,213.

To all whom it may concern:

Be it known that I, STARKY DANIEL Jonas, a citizen of the United States,residing at Georgetown, in the county of Clear Creek and State ofColorado, have invented certain new and useful Improvements inLubricators, of which the following is a specification, reference beinghad to the accompanying drawings.

This invention relates to lubricators and more particularly to alubricator which is especially designed for use upon drills'and othermachines of that character which employ compressed air as an actuatingmedium.

The invention has for its primary object the provision of a lubricatorof simple and novel construction whereby the lubricant is supplied tothe parts to be lubricated by the admission of air to the lubricantreser voir.

'A further object of my invention is, to provide a lubricator consistingof very few parts which maybe easily and quickly assembled, and onewhich is reliable and efficient in practical use and may be manufacturedat small cost,

With the above and other objects in view, the invention consists of thenovel features of construction, combination and arrangement of partshereinafter fully described and claimed, and illustrated in theaccompanying drawings, i-n'which I Figure 1 is a longitudinal section ofa lubricator embodying my improvements; Fig. 2 is a section taken on theline 22- of Fig. 1; Fig. 3 is a section taken on the line 33 of Fig. 1;Fig. 4 is a longitudinal section illustrating a slightly modified formof the invention; and Fig. 5 is a detail section taken on the line 5-5of Fig. 4.

Referring in detail to the drawing 5 designates the body of thelubricator which .is longitudinally bored at one side of its center toprovide an air passage 6 therethrough. A longitudinal cylindricalchamber or oil reservoir 7 is also formed in the body of the lubricator,one end of said chamber being permanently closed, and the other endthereof threaded to receive a-closure plug 8 whereby the reservoir maybe supplied with the lubricating fluid. In one end of the casing or body5 a hose connecting plug 9 is threaded, said plug having a longitudinalbore 9 which is alined-with the air passage 6. An air supply hose 10 isthreaded upon the other end of the plug 9 and extends to the source ofair supply. In the other end of the casing, astem 11 is threaded whichis also longitudinally bored as at 11 and communicates with the upperend 6 of the air passage 6. A coupling member 12 is arranged upon thestem- 11 and provides means whereby the lubricator is connected to thedrill or other machine at the air intake port. I

The wall 13 between the air passage 6 and the lubricant reservoir 7 isprovided with the transverse communicating ports 14, one of said portsbeing disposed in the upper end of said wall and the other intermediateof the ends of the lubricant chamber. A two-way valve 15 is seated inthe walls of the air passage 6 and is; provided with a main port 16 anda smaller port 17 which communicateswith the main port and opens uponone side of the valve. In the normal position of this two-way valve,when air is being supplied to the machine, the port 16 is longitudinallydisposed with relation to the passage 6,. as shown in Fig. 1 andcommunication between the lubricant reservoir 7 and said passage isclosed by the valve member. A suitable handle 18 is arranged upon thereduced end of the valve 15 which extends exteriorly of the body 5.

The valve is retained in its seat by means v in the body of thelubricator and is formed with a recess 20 to receive a coiled spring 21.This coiled spring'bears upon the end of the valve member 15 and forcesthe valve into frictional engagement with its seat to prevent the escapeof air between the same and the wall 13. As the valve or its seatbecomes worn, the spring 21 acting upon the valve member takes up thiswear and at all times holds the valve in close engagement with the wallsof its seat. The valve member may be easily inserted or removed bysimply removing the plug 19 and the operating handle 18.

In the upper end of the wall of the reseris disposed through atransverse screw threaded opening 27 which extends through the oilconducting member 22 and intersects the longitudinal bore thereofintermediate of its ends. The upper end of the tube 26 is provided witha knurled head 28 whereby it may be conveniently inserted and secured inits proper position. The lower open end of the tube 26 is disposedslightly above the bottom of the reservoir 7 so that the lubricatingfluid may freely enter the same in the operation of the device. Adjacentto the other end of the tube in the threaded portion thereof the same isprovided with a plurality of perforations 29 which afford communicationbetween said tube and the longitudinal bore of the tubular member 22.

In the operation of the device, the valve member 15 is rotated in itsseat from the position shown in Fig. 1 which it occupies in theoperation of the drill or other machine, so as to dispose the port 17 inalinem'ent with the port 14:, thereby reducing temporarily the supply ofair to the machine. The admittance ofthe compressed air to the reservoir7 acts upon the oil contained therein to force the same upwardly throughthe tube 26, from whence the lubricant is discharged from theperforations 29 in the upper end of said tube into the bore of thetubular-conducting member 22. From this member the oil flows through theupper bore 14 into the air passage 6. The valve is now immediatelyreturned to its normal posit-ion so as to permit of the-free flow of airfrom the source of supply through the passage 6 and, connection 11 tothe machine. The velocity of the air carries the oil in suspension throuh the connections between the lubricator an the machine to the parts tobe lubricated. Thus it will be seen that the lubricant is notdischargedall in one place but is sprayed so as to more effectively lubricate themachine elements.'- The reservoir 7 has a plug 30 threaded in itswallintermediate of its ends to provide a closure for'theopening thereinthrough which the drill extends in the boring of the port-14. The member22 closes the opening in the upper end of the reservoir wall which isprovided for a similar purpose.

In Fig. 4 I have illustrated a, slightly modified form of the inventionwherein the the conductin member 22 is disposed. This member is similarin form and construction to that used in the preferred form of thedevice with' the exception that the openings 29 are arranged thereinadjacent to its outer end instead of its center. It is believed that theoperation of this form of the lubricator will be obvious, the principleremaining precisely the same as in the preferred construction.

From the foregoing it will be seen that I have devised a very simple andnovel form of lubricator for use upon machines which employ air as theactuating fluid. The device is very simple and reliable in operation,and by simply adjusting the two-way valve, a small quantity of oil maybe supplied to the machine elements at intervals in the operation of themachine, thus keeping the parts thoroughly lubricated. Owin to itssimplicity it may also be constructe at an extremely low cost.

While I have shown and described the preferred construct-ion andarrangement of the various parts, it will be understood that the deviceis susceptible of considerable modification without departing from theessential feature or sacrlficing any of the advantages thereof.

Having thus described the invention what is claimed is 1. A lubricatorof the character described comprising a body having an air passageformedtherein and an oil reservoir arranged in parallel relation to said airpassage, the wall separating said passage and reservolr having portstherein connecting the same, a

with the other of the ports, said member being adapted to receive anddischarge the oil into the air passage when air is admitted to thereservoir.

2. A lubricator of the character described comprising a body having alongitudinal air passage therein and an oil reservoir, said reservoirand air passagebeing connected, a valve normally closing communicationbetween the air passage and reservoir and adapted to be manuallyactuated to open communication between the same at times to admit airinto the reservoir, a conducting member disposed in the upper end of thereservoir and having alongitudinalbore communicating with the airpassage, and means arranged in the reservoir connected to said membertosupply oil thereto under pressure of the air which is'adr'nitted tothe reservoir.

3. A lubricator comprisin a body having an oil reservoir therein, saibody also having an air inlet and outlet port and communicating portsconnecting the reservoir'with said air ports, means normally closingcommunication between the reservoir and said air ports adapted to bemanually actuated to admit air to the reservoir at certain times, a

tubular oil conducting member arranged in the wall of said reservoir atits upper end and communicating with the air port, a tube longitudinallydisposed in the reservoir and open at one end, said tube being connectedto the conducting member to supply oil to the bore thereof from whenceit is discharged into the air passage under pressure of the air which isadmitted to the reservoir.

4. A lubricator of the character described comprising a body having anair passage therein and an oilreservolr, the wall separating said assageand reservoir having a port therein intermediate of its ends, a

two-way valve seated in the passage to normally close communicationbetween the same and the reservoir and adapted to be manually actuatedto'open communication therebetween at certain times, said intermediatebody wall having a second port therein adjacent to one end, a tubularoil conducting member disposed through the reservoir wall and'seated inone end of said latter port, a tube disposed centrally in the oilreservoir and open at one end, said conducting member having atransverse threaded opening therein to receive the upper end of saidtube, said upper end of the tube having a plurality of perforationsopening into the bore of the conducting member to supply oil thereto.under the pressure of air which is admitted to the reservoir.
